FTP Connection problems ?
We are getting complaints on FTP connections.
Problem:
FTP connects to server but it will not show list of files or folders on ftp account.
Errors you will see in logs:
Entering passive mode (345,54,34,85,455) .
Now you won’t see further response.
Solution:
1) Login to shell
2) Edit /etc/proftpd.conf
3) You can see

# Port 21 is the standard FTP port. Port 21 |
Add following lines after above command
| Quote: |
|
# Added to make passive transfer work # use part of the IANA registered ephemeral port range PassivePorts 49152 49161 |
4) restart ftp server from /etc/rc.d/init.d/proftpd restart
5) Now we need to above passive ports range to Firewall
6) Edit /etc/apf/conf.apf
You can see following lines

# Common ingress (inbound) TCP ports IG_TCP_CPORTS=”21,25,53,73,80,143,443,110,995,2080_2099,” |
Now add passive ports 49152_49161 range to IG_TCP_CPORTS.
After adding it looks like
| Quote: |

# Common ingress (inbound) TCP ports IG_TCP_CPORTS=”21,25,53,73,80,143,443,110,995,2080_2099,49152_49161″ |
7) Restart apf firewall. service apf restart
9) Now you need to connect FTP using Passive Mode. Clients should also connect FTP using Passive Mode only.
